In 1884, the international community adopted Greenwich Mean Time (GMT) as the world's time standard. Back then, GMT was based on solar time at the prime meridian that runs through Greenwich, United Kingdom.
However, France continued to use its own standard for several decades. It was based on solar time in Paris, so local time in France was Paris Mean Time (PMT), which was 9 minutes and 11 seconds ahead of GMT. In 1911, France turned its civil time back by precisely that amount to synchronize its clocks with GMT. However, rather than officially adopting GMT as its standard time, the country now proclaimed PMT-0:09:21 as the name of its standard time zone.
Today, most of the European part of France uses a time zone that does not adequately reflect the solar time on its longitude. CET is based on solar time at 15° eastern longitude, which runs along the border between Germany and Poland. CEST, France's Daylight Saving Time, refers to an even less suitable solar time, at 30° longitude, which runs close to Kyiv, Ukraine.
